Personally speaking, as a reader, when I find a good book that's grabbed my full attention, if it's well-written and engaging, then I'm naturally going to keep wanting to turn the page. But I don't want every page to make me think OH GOD I'VE GOT TO KEEP GOING, otherwise I'll have had a nervous breakdown by the end of the first few dozen pages.
I certainly didn't suggest that. But EVERY page has to have SOMETHING to keep our readers engaged, even if it's something fairly small.

morngnstar's comments:
The term "cliffhanger" is too suggestive of the old hanging-by-the-fingernails action of old black-and-white serials. I prefer "tease." And say again that a tease should be unnecessary. If we've engaged our readers they'll turn the last page of the chapter eagerly.
If we want to include SOMETHING at the end of a chapter that is different in some way to the previous maybe-30 pages it could be a transition of some kind.
One kind could be called a tease, or hint, or promise. "They'd defeated that enemy. But there was yet another to face." This is one of morngnstar's suggestions.
But it could be the reverse: a "stop" or "period" that signifies the end of a sequence of action, such as several scenes that cover the crew of heroes and heroines fighting a company of the bad guys and defeating them.
"They'd defeated that enemy. Time now to rest for a day, or maybe a week." This suggests a slowing down of the action. You need such rest stops in a long tension-filled story.
Then the opening of the next chapter is a jump of a week or a month. We see the questers marching strongly along, spirits high. And on the horizon a trace of dust which might reveal another band of bad guys. Or it might be a peaceful caravan that they could join with the promise of adding to the caravan's protection.
This puts the cliffhanger/tease/promise/hint at the beginning of the next chapter, the opening salvo of many pages, each one pulling our readers more and more into our story.
